Definitions
- Method for producing light-guiding LED bodies from a material which is flowable before the final solidification, in a mold, the individual LED body comprising at least one light-emitting chip and at least two electrical connections connected to the chip.
- a method for the injection molding of LEDs in which the electronic parts are first overmolded in a preform in a first step.
- the preform extends to the front contour of the light-emitting light-guiding body.
- the cooled LEDs taken out of the preform are placed in a final shape in order to injection-mold the rear base parts of the LEDs.
- an LED is known from EP 0 635 744 A2, the LED body of which has a volume which considerably exceeds the volume of the conventional standard LEDs.
- the LED body is assembled from several parts in an embodiment variant. The assembly is done by gluing a standard LED into an additional, larger, transparent light-guiding body, whose task is to emit light.
- the volume of the standard LED is only a fraction of the light guide volume.
- the adhesive joint affects on the one hand by the Differences in density between the glued LED parts and the adhesive and, on the other hand, a deterioration in the light emission due to gas inclusions and different adhesive joint thicknesses.
- the LED body and the separate light guide body consist of one part. With these LEDs there is a risk of uncontrollable shrinkage during the cooling and curing phase during the casting process. With one-piece injection molding, the large injection quantity and speed make it almost impossible to prevent the chip wire from tearing off in most of the luminescent diodes manufactured.
- the present invention is therefore based on the problem of developing a method for producing light-guiding LED bodies in which almost all of the luminescent diodes produced have the same optical properties and a reject due to damage to the individual LED electronics is avoided.
- At least one flowable material is introduced into the mold at different times from one another via at least two different points.
- the flowable material is first introduced in order to flow around the chip and the connections in the area there.
- the further introduction of one or more flowable materials takes place in areas that lie outside the chip and connection area.
- luminescent diodes are injection molded in two successive steps, for example niche in a mold.
- a first step for example, a small amount of plastic is inserted into an injection mold - after inserting the electronic parts - for example from the back of the future LED.
- the quantity is just so large that the electronic parts are completely encapsulated or encapsulated. This small amount hardens quickly and thus provides good protection for the electronic parts.
- the sensitive, thin and free-standing bond wire that connects the anode to the light-emitting chip is permanently fixed and protected in its position.
- the injection molding process can be carried out with a high volume flow and high injection speed. Even an injection embossing process, which may follow this, cannot damage the bond wire.
- the materials introduced one after the other combine to form a homogeneous optical body, so that a predictable, precise light emission with minimal attenuation is possible.
- Figure 1 LED body in longitudinal section; Figure 2 top view of Figure 2; Figure 3 combined LED body in longitudinal section; Figure 4 top view of Figure 3; Figure 5 LED body in longitudinal section with a separate light guide.
- FIGS. 1 and 2 show a large-volume LED (10), the light-conducting body (21, 41) of which was produced by injection molding in at least two injection steps.
- the LED (10) shown in FIG. 1 theoretically has a two-part body.
- the lower part of the body is a so-called electronics protective body (41), while the upper part of the illustration is referred to as a light guide body (21).
- the latter is e.g. Part of the cathode (4).
- the chip (6) is seated in the reflector trough (5).
- the chip (6) contacts the anode (1) via the bonding wire (2).
- the material of the electronics protection body (41) is here a transparent, e.g. colored thermoplastic (53), e.g. a modified polymethyl methacrylimide (PMMI).
- the light guide body (21) is arranged above the electronics protection body (41). Between the two bodies (21, 41) there is a fictitious parting line (61), shown here as a wavy line in FIGS. 1 and 3.
- the light guide body (21) has, for example, the shape of a truncated cone. Its end face (22) opposite the chip (6), the so-called main light exit face, is in each case half-sided as a Fresnel according to FIG. lens (23) and as a scattering surface (24) with a scale structure.
- the main light exit surface (22) can have a simple geometric curvature depending on its optical purpose, cf. convex or concave shapes, or any free-form space surface. It can also be composed of a sum of individual regular geometric surface elements such as cones, pyramids, hemispheres, torus sections or the like.
- the side wall of the truncated cone shown in FIG. 1 is a so-called secondary light exit surface (26).
- This surface (26) can be smooth or profiled. It can also be provided entirely or partially with a transparent or opaque coating. For example, it can be galvanically mirrored as an additional reflector surface. It can take on almost any free-form surface. With smooth room surfaces, e.g. of a paraboloid inner surface, full reflection can occur even without separate mirroring.
- a first thin material (53) is first injected into the injection mold, into which, for example, the LED electronic parts (1-6) protrude from below.
- An opening in the injection mold serves as the injection point (51), which according to FIG. 1 lies at a point which is marked with a circle (51).
- the plastic (53) is injected directly under the reflector pan (5).
- this injection point (51) can be at any point on the outer contour of the electronic protective body (41).
- the outer contour here includes, among other things, a bottom surface (42) and a partially cylindrical outer surface (43).
- just enough plastic (33) is introduced into the mold that, for example, the bonding wire (2), as the most exposed component, is completely flowed around and the minimum distance between the bonding wire (2) and the parting line (61) is at least 0.5 mm. Possibly.
- a stamp can be inserted into the mold, which is moved out or moved or pivoted again before the second injection molding or casting production step.
- the shaped surface of the stamp oriented towards the electronic parts can be profiled, inter alia, in order to achieve a certain optical effect.
- the remaining volume of the mold above the parting line (61) is e.g. the plastic (53) is injected.
- the inflowing plastic (33) connects to the still viscous plastic (53) of the electronics protective body (41), if necessary it also loosens the already solidified surface.
- the crosslinking or fusion in the parting line (61) is so complete that both plastics (33, 53) form a homogeneous body. A refraction of light in the area of the parting line (61) which then disappears is avoided.
- light refraction can be achieved by using e.g. plastics of different densities can be produced in a targeted manner. Possibly. several layers of different types of plastic are injected.
- Figures 3 and 4 represent a composite LED (70) in longitudinal section and in plan view.
- Example comprises three electronics protection bodies (86-88) each including the electronics parts (1-6) and a light guide body (76).
- the electronics protection body (86-88) and the light guide body (76) are manufactured, for example, in an injection mold using the previously described method. After the spraying process, they form an indissoluble unit.
- the light guide body (76) has a main light exit opening (72) which is arranged opposite the chips (6), cf. Figure 1.
- Four secondary light exit surfaces (82-85) adjoin the main light exit surface (72).
- the composite LED (70) shown is, for example, a rear-side motor vehicle signal lighting which is integrated in the region of a side edge of the vehicle (91).
- the area in front of the electronic protective body (86) represents a direction indicator
- the area in front of the electronic protective body (87) is a brake light
- the area in front of the electronic protective body (88) is a rear light
- the secondary light exit surface (82) shown in FIGS. 3 and 4 has the function of a secondary main light exit opening. It should emit light to the side.
- An injection embossing process can be used to achieve high shape accuracy and contour precision. It is also conceivable e.g. to produce the main light exit surfaces (22, 72) with their lens and / or diffusing surfaces separately and to insert them into the injection mold beforehand. The same applies to the secondary light exit surfaces (26, 82-85).
- a separate light guide body (29) is inserted into the mold above the electronic parts (1-6).
- the light guide body (29) has, for example, still unfinished auxiliary light exit surfaces, ie its current side surfaces are not in contact with the shape.
- the Electronics protective body (41) cast or injection molded.
- the still empty spaces (28) between the electronics protection body (41) and the light guide body (29) and between the light guide body (29) and the mold are filled.
- the plastic (33) introduced last fuses the light guide body (29) with the electronics protection body (41) to achieve a high degree of dimensional accuracy and at a high cooling rate. The latter is due, among other things, to the prior insertion of the large-volume, cooled light guide body (29), which only comes into contact with newly introduced liquid plastic (33) in a relatively thin edge zone.
- An injection molding process step can also be added here.
